    Hi i just found a small cure for huge power consumption iMac 5K retina FYI.
    I just tryid a bold gaged Luxman JPA-15000 power cord(which acctually made for 100W-1000W power amps.) for iMac 5K retina(about 120W power consumption), it much improved Stax HPs sound. surprised.
    now any Stax HPs sounded much smoother and very musical.
    I googled local sites which reported stock imac power cable is not so good. it sounds light/thin/bright etc. they said.
    I measured iMac 5K retina power consumption by PS Audio power plant P3. it rapidly dynamicaly moving between about 80W-120W even when i dont touch mouse/keyboard.
    Digital signals are accutually high FREQ analog signals. uneducated poeple dont know this simple fact. maybe iMac acts like big Class D power amp. so bold gaged power cords make diffrence? maybe.

    hope this someones help.


    EDIT; i have read an interesting article which conclude directly out of walloutlet(cheapest) sounds best.

    The Portable STAX DAC/Amp is finaly available. May be this is the first Stax AMP that is of interest to me : My BHSE at home and this one during long WK...

    Seems like a considerable improvement over the SRM-252S, same voltage output voltage as the SRM-353X, but probably not as good.
  4. Rhamnetin
    I might buy one.

    Anyone heard it yet?
  6. Pokemonn
    I havent. not sold in Japan yet. I love that warmy VU meter!

    Yep I lol'd hard at the "extra enjoyment" meters from the original posting of this ad copy. Like damn, I'd better ask my T2 builder if we can work in a couple meters for more extra enjoyment! I'd hate to be left out of the fun.

    LOL extra enjoyment is not bad thing at least i guess.
    my DEQ2496 has digital LCD VU meter but it still digital, not analog meter, taste less a bit.

    Every audiophile should be jealous of your audio room dude!

    Too bad there's no line out, with pass-thru function depending on the selected source (dac or line in).

    Interesting, although the added enjoyment from a dancing meter (I assume it's the needle that is dancing) cracks me up. So, this consumes 35 watts, whereas the SRM353 consumes 30 watts, and both have the same output voltage limit. I'm guessing that the DAC uses a few watts, so the output power is probably similar to the 353. Looks like the box is smaller than a 353 so probably runs hotter.

    Can someone please help me gather all the revisions of the Omega line (SR-Omega, SR-007, SR-007A/MK II, SR-009, SR-009S)? I know that revisions exist but I do not know exactly how many of them per model as well as all the differences between them (drivers, tuning, materials, cosmetic, etc) as well as which years and serial number ranges delineate between them.

    SR-Omega (1993-1995) - two revisions?

    SR-007 (1998-2007) - two revisions?

    SR-007A/MK II (2007-present) - multiple revisions?

    SR-009 (2011-present) - ?

    SR-009S (2018-present)

    Sorry, there is no"official" info on this. Stax has never admitted to any revisions other than original SR-007 vs. SR-007MkII/A. Most of the info was posted on this thread by spritzer, who no longer posts here, about the SR007, his favored phone, so you'll have to dig it out yourself. Some of it was abstracted by Tyll Hertsens on the InnerFidelity website in his SR-007 review.

    Supposedly the best sounding SR007 variants are the early 007 and the recent (since 2015 or so) SR-007MkII with port mod. AFAIK nobody has reported any significant variants in the Sr-009, except obviously for the SR-009S.
